Find character in string: how to use strchr : String Search « String « C / ANSI-CC / ANSI-C String String Search Find character in string: how to use strchr #include <stdio.h> #include <string.h> int main
In general, the solution of this problem can be achieved by a simple program as:#include <iostream> #include <cstring> using namespace std; int main() { string s; char k; int i, c = 0; cout << "Enter String:"; cin >> s; cout << "Enter Character(a-z) : "; cin...
string::find( char c, size_type pos = 0 ) returns the index of the first occurrence of c in the string beginning at index pos. string::substr( size_type pos = 0, size_type n = npos ) returns the substring of n characters beginning from, and including, the character at index 'pos...
Learn how to find the last index of a character in a string using C++. This guide provides step-by-step instructions and examples to help you understand the concept effectively.

int find(const string &s, int pos = 0) const;//从pos开始查找字符串s在当前串中的位置 //查找成功时返回所在位置，失败返回string::npos的值 int rfind(char c, int pos = npos) const;//从pos开始从后向前查找字符c在当前串中的位置 int rfind(const char *s, int pos = npos) ...
在 C++ 里，string类型的find函数主要用于在字符串里查找特定子串或者字符。下面为你介绍它的简单用法：cpp 运行 size_tfind(conststring&str,size_t pos=0)constnoexcept;// 查找子串 size_tfind(constchar*s,size_t pos=0)const;// 查找C风格字符串 size_tfind(constchar*s,size_t pos,size_t n)const...
